Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present specification.
As shown in fig. 1, a motherboard (not shown) is disposed in the server, a hard disk backplane and a hard disk management card, such as a RAID card or an HBA card, may be plugged into an expansion connector (not shown) of the motherboard, and the expansion connector may be based on PCIE (Peripheral Component Interconnect Express) or based on other bus protocols, which is not described herein again.
The hard disk management card can acquire the relevant information of the connected hard disk and manage the connected hard disk. In order to increase the number of hard disks that can be managed by the hard disk management card, a hard disk backplane may be provided, and the hard disk backplane may include an expansion chip and a logic chip. The logic chip may be pre-programmed with a register and an operation module, where the register is used to record status signals, such as in-place signals, obtained from the hard disk. The operation module can realize data analysis, packaging and the like among the expansion chips.
From the hardware structure aspect, the hard disk management card is connected with the hard disk backboard, and the hard disk backboard is connected to the hard disk. Specifically, the memory controller is connected to an expansion chip, and the expansion chip is connected to the logic chip and each hard disk. The server can also be provided with a plurality of indicator lamps which are connected with the logic chip, and the logic chip can control the on and off of the indicator lamps through the value of a specific register of the logic chip. Interaction among the memory controller, the expansion chip and the hard disk can be performed through out-of-band signals.
After the server is started, the expansion chip may send a request message to the hard disk based on the communication protocol. After the hard disk receives the request message, a feedback message may be sent to the expansion chip, and the expansion chip then feeds back to the storage controller, so that the storage controller may detect the state of the hard disk, and determine whether the hard disk has a fault, but if the hard disk is not in place, the expansion chip sends a notification message to the storage controller after the request message is sent out time, where the feedback performed by the expansion chip to the storage controller based on the out-of-band signal is referred to as out-of-band information, that is, the feedback message includes the feedback message received by the expansion chip from the hard disk and the notification message sent to the storage controller when the feedback message of the hard disk is not received. However, when a hard disk has a serious failure, the hard disk cannot send a feedback message to the storage controller, so that the failure of the hard disk cannot be sensed, and further, an indicator lamp on the server cannot be controlled to correctly show the state of the hard disk. In this case, when the storage controller can receive the feedback message, the storage controller may identify the failed hard disk based on the feedback message, but when the notification message is not received, the storage controller may consider that the hard disk is not in place. Therefore, the storage controller cannot control the lighting of the fault indicator lamp on the server, and when the on-site indicator lamp is on, the state of the hard disk displayed by the storage controller may be considered as that the hard disk is in a normal state by a worker, so that the worker cannot find the fault of the hard disk.
In order to enable the storage controller to more accurately interpret whether the hard disk has a fault or not so as to prompt the state of the hard disk of a worker, the application provides a hard disk fault display method, which is applied to an expansion chip of a hard disk backplane, and as shown in fig. 2, the hard disk fault display method includes:
and S100, acquiring out-of-band information fed back by the hard disk.
S101, receiving the on-site information of the hard disk sent by the logic chip.
After the extension chip sends the request message based on the out-of-band signal to the hard disk, the extension chip may receive a feedback message sent by the hard disk based on the out-of-band signal, and determine the out-of-band information for one hard disk, that is, determine the out-of-band signal according to the feedback message or without receiving the feedback message. And, the on-site signal of the hard disk is obtained through the connection between the Logic chip, such as a CPLD (Complex Programmable Logic Device), on the hard disk backplane and the hard disk, and the on-site information is generated according to the on-site signal. This in-place information may be recorded by a specific register in the logic chip, which is subsequently referred to as the in-place register. The logic chip may periodically obtain the in-place signal of the hard disk, or may obtain the in-place signal of the hard disk according to an interrupt or other manners.
For example, taking the hard disk 0 in fig. 1 as an example, after the logic chip acquires the in-place signal of the hard disk 0 and records the in-place signal in the corresponding in-place indicator, the in-place indicator corresponding to the hard disk 0 may be turned on based on the state value in the in-place register, so that the worker knows that the hard disk 0 is in place.
Thereafter, the logic chip may cause the expansion chip to acquire the in-place information recorded in the logic chip based on the bus connection with the expansion chip. The bus may be an SGPIO bus, and as shown in fig. 3, may include four lines, namely, a Sclock line, a Sload line, an SDataOut line, and an SDataIn line. The Sclock line is used for providing a clock signal, the Sload line is used for triggering transmission of an SDataOut line and an SDataIn line, the SDataOut line is used for sending data to the logic chip by the expansion chip, and the SDataIn line is used for sending data to the expansion chip by the logic chip. After one Sload line triggering, the logic chip and the expansion chip carry out bidirectional data transmission.
For a hard disk, 3 bits can be reserved for information transmission, and the reserved bits can be continuously transmitted on the SDataIn line by one Sload line rising edge trigger, and the form is shown in FIG. 4. In order for the expansion chip to acquire the bit information of the hard disk, the bit information recorded in the bit register in the logic chip may occupy one of 3 bits, that is, the bit information may be sent by the logic chip to the expansion chip through the sdataiin line in the SGPIO bus. The logic chip transmits the in-place information through the first bit corresponding to the hard disk 0 in the sdataiin line, and the expansion chip can know that the hard disk 0 is in the in-place state.
S102, sending the out-of-band information to a hard disk management card so that the hard disk management card determines a first hard disk state according to the out-of-band information and generates a control signal carrying the first hard disk state.
After the expansion chip acquires the in-place information and the out-of-band information, the out-of-band information can be sent to the hard disk management card.
Then, the storage controller on the hard disk management card may determine whether the hard disk has a fault according to the out-of-band information, that is, the storage controller may determine the first hard disk state of the hard disk based on an SES (SCSI Enclosure Service) protocol according to the out-of-band information. In this first hard disk state, an out-of-band signal exception condition may be interpreted by the storage controller as the corresponding hard disk being out of place.
S103, receiving a control signal sent by the hard disk management card, and updating the state value of the indicator light register in the logic chip according to the control signal and the in-place information, so that the logic chip controls the corresponding indicator light according to the state value of the indicator light register.
Specifically, step S103, updating the state value of the indicator register in the logic chip according to the control signal and the in-place information, includes:
and S1030, determining the state value of the fault register corresponding to the fault indicator lamp according to the control signal and the on-site information.
And S1031, issuing the determined state value of the fault register to the logic chip based on the bus between the expansion chip and the logic chip.
Optionally, step S1030, determining a state value of a fault register corresponding to the fault indicator according to the control signal and the in-place information, includes:
S1030A, if the hard disk is determined to be in place according to the in-place information and the out-of-band signal is not fed back by the hard disk, marking the out-of-band signal of the hard disk as an abnormal state.
S1030B, if the out-of-band signal of the hard disk is in an abnormal state and the first hard disk state determined according to the control signal is a normal state, marking the second hard disk state as an abnormal state.
S1030C, determining the state value of the fault register corresponding to the fault indicator lamp according to the state of the second hard disk.
Optionally, step S1030, determining a state value of a fault register corresponding to the fault indicator according to the control signal and the in-place information, further including:
S1030D, if the hard disk is determined not to be in place and the out-of-band signal fed back by the hard disk is not present according to the in-place information or the hard disk is determined to be in place according to the in-place information and the out-of-band signal fed back by the hard disk is received, marking the out-of-band signal of the hard disk as a normal state.
S1030E, if the out-of-band signal of the hard disk is in a normal state and the first hard disk state determined according to the control signal is in a normal state, marking the second hard disk state as a normal state.
S1030F, if the out-of-band signal of the hard disk is in a normal state and the first hard disk state determined according to the control signal is an abnormal state, marking the second hard disk state as an abnormal state.
The hard disk backplane is connected with two hard disks, namely a hard disk 1 and a hard disk 2, and the hard disks are respectively inserted into the slot position 1 and the slot position 2, and the slot position 0 is not inserted with the hard disks.
After the extension chip determines the bit information and the out-of-band information, the bit information and the out-of-band information may be recorded in the form of a table, as shown in table 1 below.
| Slot position identification | Out-of-band signal | On-site information | Without out-of-band signal failure |
| 0 | 0 | 0 | 0 |
| 1 | 1 | 1 | 0 |
| 2 | 0 | 1 | 1 |
TABLE 1
Since the slot 0 and the slot 2 are not plugged with a hard disk, a feedback message cannot be sent to the expansion chip, and the slot 1 receives the feedback message. The in-place information of the slot 0 indicates that the slot 0 is not plugged with a hard disk, and the in-place information of the slot 1 and the slot 2 indicates that the hard disk is connected with the slot 1 and the slot 2. In table 1, out-of-band information flag is detected as 1, out-of-band information flag is not detected as 0, hard disk in-place flag is detected as 1, and hard disk in-place flag is not detected as 0.
And the expansion chip performs exclusive OR operation according to the out-of-band information and the in-place information, records an operation result and determines the fault that the out-of-band signal cannot be received under the condition that the hard disk is in place. That is, a fault without an out-of-band signal is indicated in table 1, where 0 indicates that no out-of-band signal fault exists and is in a normal state of the out-of-band signal, and 1 indicates that no out-of-band signal fault exists and is in an abnormal state of the out-of-band signal.
In the expansion chip, the following table 2 may also be recorded, and the table 2 is used to determine whether the hard disk actually has a fault. The out-of-band signal-free fault corresponds to an exclusive or operation result in table 1, and the SES state represents a fault determined based on out-of-band information. The confirmation of the actual failure may be an or operation with the SES status through the out-of-band information-free failure, so that the failure determined by the out-of-band signal and the failure in which the hard disk is in place and does not receive the out-of-band signal may be respectively exhibited in the actual failure. The SES state is the first hard disk state fed back by the storage controller according to the out-of-band information. Through the first hard disk state, the expansion chip can determine the possible faults of the hard disk which is in place and has normal out-of-band signals. The expansion chip determines the state of the second hard disk based on the state of the first hard disk fed back by the storage controller and whether the out-of-band signal determined by the expansion chip is abnormal or not so as to reflect the state of the hard disk more accurately.
For slot 0, it may be determined that the slot 0 is in the slot, and although the out-of-band signal is not detected (that is, the out-of-band signal is in the invalid state), the out-of-band signal is not detected because the hard disk is not set, so that a situation that the hard disk is connected but the out-of-band signal fails does not occur, that is, the hard disk is in the normal state.
For the slot 1, the expansion chip detects an out-of-band signal (that is, the out-of-band signal is in an effective state) and also detects an in-place signal, so that whether a fault exists in the hard disk can be normally judged by the storage controller on the hard disk management card according to the received out-of-band signal.
For the slot 2, the expansion chip detects the in-place signal, but does not detect the out-of-band signal (that is, the out-of-band signal is in an invalid state), it can be determined that the hard disk may have a hard disk fault that cannot be determined by the storage controller, and at this time, the result of the xor operation between the in-place information and the out-of-band information is 1, which indicates that the hard disk has a fault and is in an abnormal state.
